On some platforms clock_gettime may sometimes return a current
time that is earlier than a previous time. While it rarely
happens, we need cover the case anyway.

With new link management of controller buffers between
different ACL connections, it is possible that a ACL
conn would get 0 buffers - thus no profile can run.
This affects classic and LE ACL connections.

This work around allows a floor of 1 buffer as the
floor for all connection, irrespective of controller
capability.

* commit '5e808468':
  LE: Do not remove bond on encryption failure

If the encryption fails during the re-connection process with a
previously paired LE device, the pairing is removed. Thus, a single
connection failure could lead to the device be unpaired.

This patch prevents unpairing when encryption fails.

Additionally, the IRK is restored from NV ram to fix reconnection to
dual-mode devices.

  A2DP: Lowering maximum PCM frame limit to avoid audio breaks

HID reports from a bonded device can be missed when Bluetooth is
restarted HOGP report discovery is still active. Caching the
report information and loading it back when the stack resets
will ensure incoming HID reports can be processed immediately.

Change-Id: Ia33d0a845d5a4ac5aa58bd32529aeae60db4fd49

Some car kits (notably Renesas car kits used in Nissan/Infiniti models)
will throttle incoming A2DP frames if too many frames are sent at once.
This patch lowers the maximum number of frames sent per tick to not
overwhelm the remote device.

Implements a "blacklist" identifying troublesome remote devices which
may require multiple pairing attempts to succeed.

* commit '9d8df2d1':
  LE: Serialize multiple connection parameter update requests

* commit 'd8586177':
  Implement GATT service cache

When trying to reconnect a previously paired device, notifications may
be sent by the remote device before the characteristic handles have been
discovered. Thus notifications will be lost.

This patch adds a non-volatile attribute cache that allows attribute
handles to be restored before notifications are received.

  Increment seq before adding to packet in avdt_scb_hdl_write_req_no_frag

Bluetooth controllers do not allow multiple connection parameter
updates where there is one outstanding. This requires serializing
all connection parameter update requests and send the latest
request when the pending one is finished.

Bluetooth Certification Test case TP/TRA/BTR/BV-01-C for Basic
Transport Service Support fails. The failure is because the PTS
is expecting the first RTP Media Frame to have a sequence number
of 1. But metallica sends it as 0.
bug 17893538

Change-Id: Idfe7ae382c3764616dab4733cdf83b1627b8b3c9

Running GKI timer engine via JAVA alarm service was causing severe
timer preemption at times which affects A2DP media task timer. This in
turn was stressing the compensation logic towards UIPC resulting in
very bursty reads of up to 40 UIPC frames at a time. This led to
instabilities on the UIPC pipe and trickled upwards in audio framework.
Inclusion of java alarm thread in A2DP high priority thread list results
in a much smoother data flow for entire A2DP data path and improved
audio quality.

This reverts commit a934f018.

This patch caused various headset audio break issues and slow
reconnections on headsets like the Bose AE2W.

Based on the original bug under which this patch was merged
(b/10648781) it is unlikely that this bug even fixed the
issue it was meant to address.

  Revert "anthias:17614185:Bluetooth: Getbuf returning invalid buffer pointer"

This reverts commit c1ccb0d9.

This change looks like a likely candidate for the culprit behind
a wide range of BT issues we're seeing across many devices.
Reverting this in order to test.
